What is the History of the Welding Process? What are Welding Methods? What are the Types of Welding and Advantage of Welding? What Is Welding By heating two or more surfaces to a melting point, welding joins two or more pieces of metal or thermoplastic. Typically, this process involves applying heat and pressure to the surfaces being joined, causing the materials to melt and fuse. History of the Welding History of Welding Method/Process ·          Earliest stage of welding is known as forge welding ·          16th century - Soldering process used for brazing silver and copper ·          18th century - Gas welding and Arc welding ·          19th century - Fusion welding, Metal electrode welding and Carbon arc welding. ·          20th century - Electric arc welding Several new...

Steel rim step by step manufacturing process

Rims are incredibly important to the entire wheel component which means rim manufacturing plays a crucial role in the production of wheels. xiaoys’s steel wheel rim manufacturing line is used to manufacture wheel rims for passenger cars, trucks, bus, tractors, farm vehicles and construction vehicles wheels according to user’s requirements, we can design and manufacture the rim production line to make 10 to 54 inch steel wheel rims


PROCESS :-
  1. STEEL STRIP CUTTING
  2. RIM BEND FEEDING
  3. DEBURRING FOR BOTH SIDE
  4. STAMPING MARK
  5. RIM BEND COOLING
  6. FLATTENING WELD JOINT
  7. AC FLASH BUTT WELDING
  8. TRIMMING WELDING JOINT
  9. PLANISHING
  10. END CUTTING
  11. COOLING
  12. RE-ROUNDING
  13. INITIAL FLARING
  14. 1ST ROLL FORMING
  15. 2ND ROLL FORMING
  16. 3RD ROLL FORMING
  17. 4TH ROLL FORMING
  18. EDGE FLANGING
  19. FINAL EXPANDING
  20. VALVE HOLE PUNCHING
  21. PRESS DISC IN TO RIM
  22. COMBINED WELDING FOR RIM AND DISC
  23. BOLTING RIM AND DISC

FEEDING, RIM BANK COILING ( 1-4 )

A coiler machine is an essential machine that is used before the rim welding. It provides the forms for coiled hoops from flat rim bands. it can be used  in the preparation of wheels for light weight cars, trucks, construction vehicles and more. After the feeding, deburring, stamping and auto colling the rim bend will become a coiled hoop

FLATTENING, BUTT WELDING (5-6)

It is necessary to use the flattering machine to flatten the joint of the coiled rim bands that are over 4mm thick before proceeding to the flash butt welding process

TRIMMING, PLANISHING, END CUTTING (7-9)

The welding slag will be produced on both the inside and outside surface of the weld joint after the welding process. A special machine unit comprised of the trimmer, planisher and end cutting machine can be used to remove the slag and make the surface of the weld joint flat smooth

FLARING (10-12)

After the weld joint processing, cooling, and re-rounding processes, a horizontal flaring machine will be used to flare two edges of the rim to make the following roll forming processes easier.

ROLL FORMING (13-16)

The roll forming machine is used for the symmetrical roll forming of wheel rims for passenger car, tractors and construction vehicles. This machine is used for the 1st through the 4th roll forming. the 4th roll forming process is optional, and is used to press non-skid patterns onto the rim of tractors and construction vehicles.

EDGE FLANGING, EXPANDING (17-18)

A horizontal expanding machine is used for the expanding size process after the roll forming of the wheel rims. Precise expanding and sizzing using a special tooling allows the formed rims to meet the design requirements for diameter.

      GAS TIGHTNESS TESTING, VALVE HOLE PUNCHING (19)

            Gas tightness detection tests are conducted to ensure the welding quality and reduce air leakage. The valve hole punching is done after profiling, and is an important step wheel rim manufacturing . With a corresponding molcl. It can punch the right valve hole on the effective part of the rim. The valve hole punching press is used for the flat pressing and hole punching on tubeless wheel rims.

PRESS DISC INTO RIM , WELDING ( 20-22)

            A steel wheel is made of the wheel rim and the weel disc . The wheel rim and tire form an alright unit for bearing the vehicle’s weight and transmitting power. The wheel disc is connected to a hub and transmits the power from the engine. Usually , the wheel rim disc of passenger car and trucks are connected by welding, whereas large wheel rims and disc for tarm vehicle’s are bolted to each other

DP Test

How DP Test Works??? Dye Penetrant Examination is commonly used for weld components. In this technique low viscosity liquids are allowed to penetrate in the surface openings and after penetration, liquid is made to extract out again by means of some developers. That is why it is also known as Liquid Penetrant Examination for the evaluation of weldment.  The examination includes five steps ·         Cleaning ·         Introducing Penetrant ·         Penetrant Removal ·         Introducing Developer ·         Examination Cleaning: - To start, the test surface is need to be cleaned with the help of wire brush or some old cloth using a suitable. cleaner. The surface must be cleaned from organic compounds (oil and grease), dust, scale and other pollutants because an even su...
